Carbon from Lignin and Sodium Lignosulfonate
Carbon from Lignin and Sodium Lignosulfonate ，need to make clear the Applications for lignin and lignosulfonates are limited today due to the undefined structure and varying properties of the substance. However, lignin, as the second most abundant bio-resource besides cellulose and the bio-resource with one of the highest natural carbon contents, has the potential to…

Lignosulfonate(Lignosulphonate)
Lignosulfonate(Lignosulphonate) are obtained from sulfite pulping processes wherein cellulose is extracted from wood in the pulp industry. The so-called sulfite pulping process involves mixing sulfur dioxide (SO2) with an aqueous solution of base to generate the raw liquor for cooking the wood. In water, the sulfur dioxide forms sulfurous acid (H2SO3), which degrades and eventually sulfonates the lignin by…

Lignosulfonate(lignosulphonate)
Lignosulfonate(lignosulphonate) (often abbreviated as LS) were one of the first dispersants added as an admixture to concrete. Lignosulfonates have been used since the 1930s as plasticizers or water reducers. Mixed with concrete, their use has afforded the beneficial effects of retarding the setting time and reducing the amount of mixing water required. The only lignin…

Lignosulfonate work as super plasticizer
Lignosulfonate water-reducing agent is a surfactant. Therefore, the mechanism of action is lignosulfonate surfactant effect. Surfactant is an organic compound whose molecules have both hydrophilic and hydrophobic two groups. The hydrophobic groups are various alkyl or alkyl aryl group; hydrophilic group is generally able to dissociate the ionic salts. According to the hydrophilic group of…

Lignosulfonates used in agriculture
Potassium Lignosulfonate and Ammonium lignosulfonate can be used in agriculture Soils treated with ammonium lignosulfonate generally had lower pH than untreated control soil (Fig. 1A). The pH reduction was greater with 0.5 and 1.0%, than with the 2.0% ALS mixture. All ALS treatments caused an increase in total soil bacterial population (Fig. 1B). In general,…

Lignosulfonate used for dust suppression
A more environmentally friendly solution is organic sulfonates like lignosulfonate. They are byproducts of the lumber industry and control dust in the same manner as hygroscopic salts. The major difference is that the material, which looks like molasses is organic, non-toxic, and won’t control equipment. In order to find the best dust control agent, the…
